Description

A kind of cement grinding mill end plate connection structure

Technical field

The utility model relates to cement grinding mill fields, and in particular to a kind of cement grinding mill end plate connection structure.

Background technique

In the prior art, cement grinding mill mostly uses welding structure to guarantee its intensity, and end plate at cylinder and its end plate connection It mostly welds to form L-type welding structure as shown in Figure 5 with body end surface.The structure welding is simple, but because plane where weld seam It perpendicular to cylinder axial direction, and is only to be connected by welding portion between end plate and cylinder.Cylinder can frequently turn at a high speed when work It is dynamic, it will receive the pulsating stress that cylinder rotation generates at cylinder both ends, stress is concentrated in welded seam area in the existing structure, Weld cracking is caused after a period of use, to reduce the service life of equipment, increases the frequency and cost of maintenance.Cause This needs a kind of cement grinding mill end connecting that can be reduced stress suffered by end plate weld joint region now.

Utility model content

The purpose of this utility model is to provide a kind of cement grinding mill end plate connection structures, to solve the weldering of prior art end plates The weld seam of binding structure is easy centralized cycle stress, is easy to split, and reduces service life of equipment, increases asking for maintenance frequency and cost Topic.

The cement grinding mill end plate connection structure, including cylinder and the end plate for being welded on the cylinder both ends, the end plate With the cylinder inboard wall clearance fit, it is welded on the inside of the barrel end, there are certain intervals with the body end surface, it is described Weld seam corresponding with the end plate is equipped on the inside of cylinder.

Preferably, the shallow slot along end plate circumferentially extending is offered on the cylinder, along the shallow slot in the end plate Outside is uniformly distributed several reinforcers, and a part of the reinforcer, which is inserted into the shallow slot and is had, is bonded weldering with the end plate Another part of the planar section being connected together, the reinforcer is in contact perpendicular to the planar section and cylinder inside And it is welded on the cylinder.

Preferably, the reinforcer is L shape, and shape of the planar section with the shallow slot in the side matches.

Preferably, the reinforcer is T shape, and shape of the planar section with the shallow slot in the side matches, described Planar section further includes that upward stretch out welds together with the end plate.

Preferably, the reinforcer has the cambered surface matched on the inside of the cylinder with the cylinder contact portion.

Preferably, the interval between the reinforcer is not more than 30mm.

Utility model has the advantages that end plate is welded on the inside of barrel end, end plate and cylinder junction form T-type Structure, although pulsating stress is also concentrated in end plate periphery welding position, end plate can be by stress transfer to cylinder inside, by cylinder Body supports, and weld seam not will receive larger stress, ensure that the service life of end plate Yu cylinder coupling part, reduces maintenance Number and cost, solve the problems of the prior art.

Additionally due to end plate may also by inside impact therefore, if having been added on the outside of end plate with barrel soldering part Dry reinforcer, reinforcer are welded on end plate and cylinder, form integral structure.Reinforcer can on the outside weld end plate in this way Region carries out effectively reinforcing further improving the bonding strength and reliability of end plate.
